COMBINED LIGHT AND STRUCTURE.

Application filed February 27, 1926. Serial No. 91,191.

My invention relates to combined light and structure devices and isparticularly adapted for use in connection with a telephone. Forconvenience, the invention will be described and illustrated as so used,but it is to be understood that such use is only an example of how theinvention may be used to advantage and that it is not limited to thisparticular use.

Subscribers telephone sets of the desk set type with a substation dialmounted on the base are frequently used on desk or tables where the onlysource of light available is that furnished by the usual source ofillumination for the room in which the set is situated, which source isnot favorably disposed for most convenient use of the dial and thetelephone directory, memorandum pad, etc., frequently used inconjunction therewith, due to remoteness of the light source and theshadowing of the instrument by the user or nearby objects.

I. It is the main object of the present invention to overcome thisinconvenience by the provision of an electric light and structure,preferably with a self contained source of current,

arranged in such cooperative relation with the combined desk set anddial as to permit convenient use of the instrument independently of theusual source of light with maximum economy of current supply and maximumefficiency in the use of the instrument and associated directory,writing paper, etc.

A further object of the invention is to provide a device of the abovetype so constructed and arranged that the proper method of using thesame will be readily apparent without special instruction.

Other objects of the invention will be aparent from a perusal of thefollowing specil0 cation and the drawings accompanying the same.

1n the drawings:

Fig. 1 is a side view of a telephone desk set and dial equipped with adevice embodying one form of my invention,

Fig. 2 is a fragmentary side view of'the de vice per so slightlyenlarged and partly 1n section,

Fig. 3 is a front view of the upper portion of the lamp holder removed,

is a front view of the pivoted movable bracket lamp holder removed. 7

Referring to the drawings detail, 1 indicates a telephone est setcomprising the usual base 2, post 3, transmitter 4, receiver 5 supportedon the switch-hook 6, and a substation dial 7 mounted on the base 2.Secured to the telephone post 3 by any suitable means is my novelilluminating device indicated in general by the numeral 8 andcomprising, in the illustrated example, a battery casing 9, mountingclamp 10, and spot light 11 mounted on the casing by a universal-jointconnection permitting the spot light to be swung out from the positionshown into the dotted line position and further in front or to eitherside of the telephone set. Clamp 10 in the present instance is a springclam fixed to the casing, enabling the same to be readily applied to orremoved from the telephone post. The battery casing 9 may be a standardpocket flash-light casing as indicated in Figs. 1 and 2, having alatched door or cover 12 to permit the insertion or withdrawal of abattery, with a threaded socket 13 and a switch 14 for controlling thebattery circuit. One terminal of the battery 15 is connected to the bodyof the casing and the threaded socket 13 in the usual manner not shown,while the other terminal 18 of the battery makes contact with thecontact 17 of a single conductor attachment plug 16 engaging in thesocket 13 of the casing.

A main lamp bracket 19 is secured to the side of the battery casing inelectrical connection therewith and at its upper oil-set portion carriesa movable bracket 20 mounted thereon by a pivotal mounting indicatedgener-ally by 21, bracket 20 in turn supporting a lamp holder 22pivotally mounted thereon by pivotal bearings 23. It should be observedat this point that, within the broad scope of the invention, the bracket20 can be supported directly by the telephone standard or similarsupport and that, although I have shown a self-contained source ofcurrent, this is not essential as any other source of current may beused. The pivotal axis of the lamp holder 22 and that of the movablebracket 20 are arranged at right angles to each other to form a set ofgimbal bearings for the light holder to permit universal movementthereof. The arms 20 of the movable U-shaped bracket 20 are joined bydisk or washer shaped yoke 24 (Figs. 1, 2 and e) which moves about thehollow bolt 25 constantly in electrical contact with the bracket 19,while the shank of the bolt 25 is insulated from the members 19 and 24by the insulating bushing 26 which tor convenience in assembling may bebuilt up as a collar and washers of insulating material as indicated inFig. 2, the whole being clamped between the head of the bolt and the nut27. Nested in the hollow bolt 25 is a spring tensioned contact brush 28arranged to contact with the spherical head of the lamp holder 22. Thehead of the lamp holder 22 is provided with an arc-shaped contact member29 (Figs. 2 and 3) insulated from the body of the holder by theinsulating block 30 and held in place and electrically connected throughthe conductor rod 31 to the center contact member 32, the conductor rodbeing secured in the holder and insulated therefrom by the bushing 33.The center contact member 32 is the usual form of spring-pressed contactmember similar to the brush member 28. The lower portion of the lightholder 22 forms a threaded socket 34 for the reception of a lamp 35whose base contacts make connection with the socket and central contactmember 32 in the usual manner as indicated in Fig. 2. To complete thespot light structure a cylindrical lamp casing 36 provided with a lens37 is arranged to telescope over the socket member 34:, as clearly shownin Fig. 2, the casing 36 being split part way down from its upper oropen end as indicated at 38, Fig. 3, to produce a resilient clampingengagement between the telescoping members. This adjustability of thecasing and its lens enables the light from the lamp 35 to be changedfrom a relatively wide beam to a narrow beam with consequent variationin intensity of illumination.

As the socket member 3a and lamp holder 22 are of metal and are incontact with the movable bracket 20 through the pivotal bearings 23,electrical connection is extended from the battery casing 9, which formsone terminal of the battery when switch 14: is closed, through thesupports or brackets 19 and 20 to the lamp holder and lamp socket. Fromthe other terminal 18 of the battery, electrical connection is extendedthrou h the attachment plug 18, conductor 39 an hollow bolt 25 to thebrush member 28 from which, when the contact member 29 is moved intoengagement therewith by movement of the lamp holder, this connection isextended through "ontact 29, and rod 31 to the lamp-engaging contact 32.

In operation, with the several parts in the position shown in Figs. 1and 2, the lamp circuit is open because the brush contact member 28 isresting against the insulation block 30 out of contact with the arcuatecon tact 29. l fhen the spot light is moved forward for use, the lampholder 28 is rocked about-its pivotal bearing 23 which moves thearc-shaped. contact member 29 into engagement with the stationarycontact brush 28, completing the energizing circuit of the lamp arcane?35 which may be traced from the battery terminal plug 16 throughconductor 39, hollow bolt 25, brush 28, contact 29, rod 31, contact 32,lamp 35, socket member 3st lamp holder 22, brackets 20 and 19, andthrough the battery casing 9 and switch 14 to the other terminal of thebattery. The lamp will remain lighted through a predetermined angularmovement about the bearing 23 and will not be extinguished by movementabout the pivotal bearing 21. With the lamp 35 thus energized, the widthof the beam may beadjusted according to the object to be examined bysliding the lamp casing on the lamp socket while its direction may beadjusted to any desired angle by virtue of the universal joint or gimbalbearing support formed by the different pivotal connections. After use,the operator, by moving the spot light back to the position shown inFigs. 1 and 2, or to the opposite of this position, causes the contactmember 29 to again move out of engagement with the brush 28, opening theenergizing circuit of the lamp 35. Switch 14:, it will be observed,provides additional means for making and breaking the lighting circuitand in some cases it may be desirable to control lighting of the lampwith this switch, either alone or in conjunction with the other switch.

An advantage of the ability to focus the light from a wide beam to anarrow intense beam is that for careful examination of small objects orcharacters the intensity of light may be increased by reducing the areaof illumination to an amount commensurate with the magniture of theobject examined, thus affording means for increasing the degree ofillumination Without an increase in energy supply which is a markedadvantage where the energy supply is limited, as in a battery lamp ofthe portable type.

llt is to be understood that various changes in the device abovedescribed may be made without departing from the broad scope of theinvention.
